Abstract. In this paper, we experimentally study the manipulation of the atomic spin polarization of rubidium atoms via optical pumping beams in resonance with both D 1 and D 2 transitions. In the presence of buffer and quenching gases, the D 1 pumping beam with σ + polarization creates atomic spin polarization along the direction of the beam, while the D 2 pumping beam creates …
